i need a help on how to find the local truncation error of a hybird block method of three order IVP. here is the one of the discrete methods i need to find the local truncation error. please any solution should put here thanks 

Please can someone help with maple comand to obtain Jacobian elliptic functions particularly in code editing region?

this equation is complicated

how to dsolve for this equation for function f ?

f(t,x,diff(x,t)) - f(t,x,p) - (diff(x,t)-p)*diff(f(t,x,p), p) = tan(t)

I would like to publish a technical paper about a renewable energy with you. I use Maple 2016. What i need?. Thanks!

im stuck here also still produces output but yeah  oh well :

Download MAPLE_BITTY.mw

I have a very large set of equations that calculates for a long time. Up until now, I have designated the second derivatives and copied the finished equation to another program to do the simulation. But with this file I can hardly do anything because the equations are too long. Even saving a file after computation is not easy. Export to PDF takes 20 minutes and the file has 120 MB and 1000 pages. Recording to .mw has not gone yet due to the occurrence of a write error message. I have 16 GB of RAM and after calculation is 14 GB in use.

Any suggestions?

I was wondering if it were possible to call only the mapping function used to grahically display using a particular plot command in general, but aside from that, this is the one in specific id really like, naturally, since thats a bit of a hole in the understanding of what you are looking at thats probably important in some way to something.

Sorry yes as the title suggests, id like to know how to execute keyboard and mouse pad actions in an automata of sorts.

In the help page for invlaplace we find the statement
"If the option opt is set to 'NO_INT', then the program will not resort to integration of the original problem if all other methods fail.  This will increase the speed at which the transform will run."

This statement is found in Maple 2017 and in Maple 8 and I believe in all versions in between.
Can anyone provide an example of a function F(s), where
invlaplace( F(s) ,s, t, NO_INT);
gives a different result (or works faster) than
invlaplace( F(s) ,s, t);
?
## It should be added that an identical statement is made in the help page for laplace itself.

Hello!
I have a problem with calculations. I have a worksheet and it calculated on some computer but on another i have an error after each equation. I dont have any idea why. When i click on error i see "Sorry, we do not have specific information about your error. " What can i doo with this?

salute ! all Maplesoft managers and employee programers ...

Is there any fortune in near future to have some kind of machin based "Proof Assistant" as built in part of Maple IDE ?

it can be better than COQ ?

also there is a great lack of user interactivity by Geometry and Geometry3d packages of maple !!!

for example most of the time it is nessesary (and more facilated) to define geometrical primitive shapes manually or making simple transformations and dissectings attaching ... rather than doing them programaticaly or by commands ?

even having traditional tools like compass ruler ... in pallettes of Geometry window ?

BEST WISHES FOR MAPLESOFT

I'm trying to solve Laplace's equation in Maple in 2-D domain. But while writing the last line "pdsolve(pdef)" (to get the final solution) and after that hitting enter, it doesn't shows anything. Please help me regaring this.

f := -ln(-1-ln(exp(x)))+ln(-ln(exp(x)))-Ei(1, -1-ln(exp(x)))+Ei(1, -ln(exp(x)))
solve(limit(diff((subs(x=q, f)-f),h), h=0) = f, q);
limit(diff((subs(x=x*h, f)-f),h), h=0);
Error, (in limit/dosubs) invalid input: `limit/dosubs` uses a 3rd argument, newx, which is missing

guess an operator called Lee, Lee(f, x) = f

solve(limit(diff((subs(x=q, f)-f),h), h=0) = f, q);

suspect q = x*h or q=x*f
